Difficulty : Steel Path
Void Fissure (Lith)
Map : Augustus (Mars)
Mode : Excavation
No extraction point was available after opening 1 relic.
I even reached the usual section of the map where extraction should be and nothing happened. (so it's not just a marker bug)
I repeated the mission and got the same exact extraction bug.
In both cases I had to abort mission and lost all my loot.
